Leap Day () is a Hong Kong television drama series created by HK Television Entertainment and broadcast on ViuTV from 2 to 13 March 2020. Under the direction of Steve Law and penned by Yellow Wong, the cast features Sofiee Ng, Chui Tien-you, and Terrance Lau in leading roles.

Synopsis

Yeesa Cheung (Sofiee Ng), whose birthday falls on leap day, considers her birthdate to be between 28 February and 1 March during non-leap years. While celebrating in 2017, she unexpectedly travels through time to 29 February 2020 in Sapporo. There, she encounters two strangers, Ryan Ma (Chui Tien-you) and Yu Ka-chung (Terrance Lau), and learns that her future self has perished in a traffic accident. Returning to 2017 with only a second having passed, the trio must work together to change their intertwined destinies.

Production

The production team identifies the series mainly as a romance rather than science fiction. Director Steve Law drew inspiration from a friend born on 29 February and integrated time travel into the narrative. Filming wrapped up in Hong Kong prior to overseas shoots. Originally set in Taipei, the storyline’s setting was relocated to Sapporo to amplify its enigmatic and romantic atmosphere. The Sapporo Film Commission assisted in casting Japanese actors, with Yamano Hisaji, coordinator of the Japanese production company, taking on a significant role.

Due to budget constraints and a tight filming schedule, certain scenes utilized computer-generated imagery, and some plot points, such as Kagawa’s conclusion, were omitted from filming. The elaborate crash sequence in Episode 9 required a storyboard visualizer—a rarity in television—to facilitate smooth execution. Post-production was completed just three days before the finale aired.

Actors Sofiee Ng and Terrance Lau accepted their parts based on previous collaborations with the crew, without reviewing the script beforehand. During a chase scene filmed in Sapporo, Ng suffered three torn ligaments but continued with filming.

Theme music and song

The soundtrack, including the opening and closing themes, was created by Day Tai and his team at D Dome Music.

Prequel and sequel

During the ViuTV 2021 event held on 17 October 2020, the network unveiled 940920, a drama inspired by the secret code shared between Yeesa and Ka-chung in Leap Day. Featuring the same production team and starring Sofiee Ng, Terrance Lau, and Cecilia Choi, this series functions as both a prequel and sequel, exploring two parallel universes centered on Ka-chung. The teaser depicts Choi’s character inviting Ka-chung to join the Sacred Geometry Association she established, while Yeesa chooses to stay in a universe where she remains unfamiliar. Initially scheduled for filming in Hong Kong and Yilan, Taiwan during spring 2021, production was postponed due to the global COVID-19 outbreak. In May 2021, Law revealed that the script was revised to focus solely on Hong Kong because of force majeure, with filming commencing in September.

940920 debuted as a ten-episode series on ViuTV on 7 March 2022.
